Makhlad bin Uqbah bin Shurahbil transmits, through his grandfather Abd al-Rahman, the statement of his (Abd al-Rahman's) father: "I came to the Prophet (peace and blessings be upon him), and there was a sil'ah (a type of cyst) on my palm. I said: O Prophet of Allah! This sil'ah has made my hand swollen, and it has become an obstacle between me and the hilt of the sword, preventing me from gripping it, and from holding the reins of my mount. The Prophet (peace and blessings be upon him) said: Come near me! I came near him and opened my hand. Then he blew into my palm, then he placed his hand on that cyst and kept pressing it, until when he lifted his hand from it, I could not see any trace of that cyst."
Al-Tabarani recorded it. I do not know Makhlad and the narrators above him; the remaining narrators of this narration are the narrators of the Sahih.
